That's right.
This also works with "partial rows". At each step,
you can choose which subset of columns to retrieve.
(useful with a wide table, where you're only
interested in some of them).

It should (assuming those are the index objects).
I did say "normally" above :-)

$ man snmptable

-Ci This option prepends the index of the
entry to all printed lines.

OK - If I get the chance, I'll have a look at that, and see if
I can spot anything wrong.

Correct.

Check the agent code - what does it return when asked for an OID
that happens to belong to an index object? It ought to completely
ignore such object - just as if they don't exist at all.

The MIB objects referenced in the INDEX clause of the table
definition. These would normally be defined as "not-accessible",
and the agent shouldn't return values for these OIDs.
